Note: To use this feature, you must update the firmware of iDRAC to 1.51.51 and later, and Lifecycle Controller to 22.214.171.1240 and later.
LifeCycle Controller now supports updating 64-bit DUP using catalog update. The latest catalog file carries both 32-bit and 64-bit DUPs. If both the 32-bit and 64-bit DUPs are available in a catalog, preference is given to 64-bit DUP for the firmware update. 32-bit DUP is used for firmware update only when 64-bit DUP is not available in a catalog.
